Not sure what to do...

I’ve been with my husband a total of 6 years, married 4. He has lied and cheated so many times throughout our relationship. Example: would literally swear to me he isn’t doing anything and that night be texting another girl how hot she is or how he loves her etc. on our wedding night he was texting his other girls. They were all online relationships as far as I know and I stayed for the kids always.. well this morning I find out he has Facebook again after not having it for about four or five years or so I thought. I don’t have Facebook because I just don’t care about social media. We actually just had a chat about it a few weeks ago and he was so anti Facebook. To find out he actually has one and has lied about it and kept it a secret... I just feel betrayed again in all the ways he has in the past. Should I confront him? I just honestly don’t know anymore
